BROOKLYN, Ohio - Local and federal law enforcement agencies are searching a Brooklyn ravine Monday afternoon as part of the ongoing investigation into a Lakewood woman's disappearance.

Lakewood police, the Cleveland FBI and the Cuyahoga County Medical Examiner's Office are at the ravine, located along a stretch of Big Creek that sits south of Memphis Avenue and east of Tiedeman Road, Lakewood police spokesman Capt. Ed Hassing told cleveland.com.

Searchers found a container that may have "biological remains" inside, Hassing said. The medical examiner's office will take possession of the container and determine what's inside.

"The investigators and our office are of the belief that Ms. Al-Dhannoon is in fact deceased," Thomas said. "Investigators are currently of the belief that, at minimum, this is a kidnapping, and probably a homicide."

Al-Dhannoon's husband, Fahad Saeed, was arrested after his estranged wife went missing. He was charged after it was found that he violated a protection order that she had against him, and he pleaded guilty in Lakewood Municipal Court.

Saeed is currently serving a six-month sentence in Cuyahoga County Jail. He is not accused of hurting Al-Dhannoon.
